It occurs to me that another spelling could be NoError (or _noerror
where not using camel case). There's some precedent for that already;
and where we have it, it has the same implication of reporting rather
than throwing certain errors, without making a guarantee about all
errors. For instance lookup_rowtype_tupdesc_noerror won't prevent
throwing errors if catalog corruption is detected inside the catcaches.
I'm not sure this is any *better* than Safe ... it's longer, less
mellifluous, and still subject to misinterpretation. But it's
a possible alternative.
